How would I solve this?

Line BD bisects angle ABC, angle ABC = 7x. Angle ABD = 3x + 25. Find angle DBC.

So, I drew what it would look like. I'll draw it in the comments as well. Then, I did the following:

7x = 3x + 25
subtract the 3x on both sides
4x = 25
divide both sides by 4
x = 6.25

However, when I inserted x's value into the problem I didn't get the right answer. What did I do wrong?

Choices:
o50
o125
o75
o175
